Password reset flows are one of the most attacked surfaces in any application. In FormSync, we designed a reset password system that is secure by default and impossible to bypass.
Why Password Reset Security Matters
A weak reset flow can allow attackers to hijack accounts without knowing the original password. OTP reuse, URL token trust and client-side validation are common mistakes.
OTP Verification Without Bypass
In FormSync, OTP verification happens strictly on the server. After verification, the server issues a short-lived, single-use reset token. The frontend never decides access.
OTP is only proof of identity. Authorization always comes from the server.
— FormSync Security Principle
Temporary Reset Tokens Explained
Once OTP is verified, a reset token is generated and must be passed to every protected reset endpoint. Without it, the reset password page is blocked entirely.
Next.js Optimized Architecture
We leverage Next.js App Router, server components and route-level protection to ensure reset pages cannot be accessed directly or refreshed without validation.
Final Thoughts
Security is not an add-on. By designing reset flows with tokens, expiry and server validation, FormSync ensures user accounts remain protected by design.
